本文用 XPS 研究了十四种芳基重氮盐及其与18-c-6(1)和二苯并-24-c-8(2)的配合物.结果表明,重氮盐中α-N1s 和β-N1s 结合能的化学位移大小与 R 有关.重氮盐与冠醚以β-N 向醚氧提供电子(β-N→O)而配位的,而醚氧 O1s 结合能降低多少似可反映配合物的稳定性.
In this paper, 14 kinds of aryl diazonium salts and their complexes with 18-c-6 (1) and dibenzo-24-c-8 (2) have been studied by XPS.The results show that α- The chemical shift of the binding energies of N1s and β-N1s is related to R. The diazonium salt is coordinated with the crown ether by β-N to the ether oxygen to provide electrons (β-N → O), while the decrease of the ether oxygen O1s binding It may reflect the stability of the complex.
